Cannot install windows via bootcamp (Imac Mid 2011)

Hi, I struggled for the last 2 days and can't seem to find how to create a windows partition and installed it.

Note: I have a 27 inch mid 2011 Imac and run MacOS Sierra 10.12.

I have problems with bootcamp especially at the stage of the process USB drive.

1. I do not understand why Bootcamp assistant 2 display only tasks being #1 download the windows software and #2 install windows 10 when all apple support pages show 3 different tasks available as here ://

2. I prefer to install windows 7 on my partition, bootcamp, however 'install windows 10', which means that I can't install an older version on my partition? I tried to install windows 7 via a win7 .iso file AND a win10 .iso but none of them works.

3. whenever I try to install windows, the system do not recognize my USB (it would be with .iso win10 associated drivers or Win7 .iso. + drivers associated) and constantly asking for a disc to be inserted.

My USB has been formatted through disk as MS-DOS (FAT32) volume and all utility used .iso comes from Microsoft. I don't understand why I can't have my. ISO recognized by the system.

Help please :)

This is normal and expected behavior. Your 2011 Mac does not support the USB Windows installation. You must use a physical DVD burned ISO. Your Mac does not officially support Windows 10. The ISO files are available at .

Documentation on Apple's site shows not all models. Please visit for an older version (FC5).

  • Cannot install Windows 10 on iMac

    Hey there,

    I have an iMac (27-inch, late 2013) running El Capitan 10.11.4 and have recently tried to install Windows 10. I have 8 windows running, but it crashed and I thought I would upgrade just to 10 for the sake of ease.

    So far, I made all the necessary steps. I run boot camp and the partition of the drive and tried to install it on both the USB that came with 10 windows and creating installation media downloaded from the Windows on a USB 2.0 website. When I get to the screen to select which partition to install on it comes up with an error message saying that it cannot be installed because the disk is a GPT (photos below) format, even after clicking on format. I also tried partitioning using disk without success.

    Someone knows how to fix this?

    I saw on the previous discussions to make a few Terminal commands for the following and hope these helps:

    Hi guys!

    I have a Macbook Pro 15ich Early 2011 Intel Core i7 2 GHz 16 GB RAM disk 'Captain' with dual operating system, Samsung SSD 840 EVO drive, and HARD drive that came with the laptop is my auxiliary drive.

    I have two problems.

    (2) I can't do the Boot Camp with USB I did a DVD with an external DVD drive. I can make the partition, but my problem comes when my Mac reboots to install W7 and W8 and typical black screen of MSDOS with the underscore "_" appears flashes all the time. I waited for minutes, hours, day and the laptop do not respond.

    What can I do?

    Kind regards

    During the installation of Windows Setup started and you have the screen which shows your partitions and to choose one, you choose your Bootcamp partition and click on Format of below the list of partitions? You must leave the configuration format the Bootcamp in NTFS partition before installing Windows actually.

  • Cannot install Windows on Bootcamp after replacing 3 TB FusionDrive with 1 TB SSD

    3 merger to drive has been replaced by 1 TB SSD drive. When reinstalling OS X I see that the 128 GB drive of Fusion is still available as a hard disk, which prevents me to install OS X or Windows (Bootcamp) on the SSD.

    I tried a few ways to install:

    1. OSX on SSD (recovery Internet Mode, delete all partitions and repartitioning, SSD)
      Installation fails when you try to install
    2. OSX on FusionDrive (128 GB), Bootcamp on SSD
      OSX installs fine, Bootcamp does not work. First time (10 Windows) I got an error message i/o failure and winload.exe, second time (8.1 Windows) a back message with 'failed to load the operating system, press CTRL + ALT + DELETE. That part a few times.
    3. OSX on FusionDrive (128 GB), Bootcamp on same drive
      Working, but limited to 128 GB for OSX and Bootcamp
    4. Make the logical Volume (fusiondrive) with 128 GB and 1 TB
      OSX works, but can not give more than 64 GB to my Bootcamp. Bootcamp to 64 GB ok.
    5. OSX on FusionDrive (128 GB), Bootcamp on FusionDrive - to SSD with Winclone
      8.1 clean Windows Installer, Sysprep. Everything looks ok in Winclone. When you try to reboot I get a message similar to "failed to load the operating system

    I would like to at least 800 GB on my Bootcamp. Does anyone know how to make this work?

  • Error: "could not create a new partition or locate a" when installing Windows via Boot Camp 10

    This error occurs on my 2012 15-inch MacBook Pro. I have 2 hard drives. One dedicated to OSX and one for Windows. This is my first install bootcamp. I let bootcamp create partitions, but to the partition/disk screen hard to choose, I get a message saying: "we could not create a new partition or locate a.. The partition has been formatted to NTFS. I tried later in this guide community post here: error: "we could not create a new partition or locate and existing" install Windows via Bootcamp 8.1, but no luck. I even tried to delete the partitions and create a partition empty for windows so it can create and format on its own and start using EFI. At this point, windows begins to install it and restart, but it fails during the part material recording and restarts. Then when it starts again I get a message that the installation has failed.

    Here's some output terminal which can help you to (I) hope.

    You must disconnect the internal bus 500 GB SATA drive and use a flashdrive USB2 for OS X from startup. The 320 GB designated drive must be in the main Bay of the Mac. Once Windows is installed, reconnect your 500 GB drive in the Optibay (if you this road main Bay) will be Windows blue screen in most cases.

  • Windows 7 fails to install completely via Bootcamp on El Capitan

    Configuration information:

    iMac: 27-inch, late 2009, with an internal optical drive

    HDD capacity: 1 TB, 593 GB available (after Windows 96 GB)

    OS: El Capitan, 10.11.2

    Processor: 3.08 GHz, Intel Core 2 Duo

    RAM: 8 GB

    Boot Camp: 6.0.1

    Windows 7 Professional, SP1, 64-bit

    My Windows 7 installation does not end, stopping somewhere on the last phase that says "end Installation." I had Windows 7 installed on my Mac before El Capitan has been installed and it worked fine (using the 32-bit version then - I tried too after the installation of El Capitan, but that doesn't work anymore). I did a fresh install of El Capitan that then tried to reinstall Windows 7, but nothing has worked, as shown below.

    I use Bootcamp 6.0.1 to install Windows 7 Professional (full version) on a DVD via the internal optical drive. Bootcamp does not offer the ability to select an ISO file. My selection select Bootcamp task shows that these two options:

    -Download the latest software from Apple's Windows support

    -Install Windows 7

    I chose the two options and had the software support installed on a 64 GB USB key. Since the only option after that install the software support is to stop BCA, I did. I've reopened BCA, deselected the option to download the support software and continued to install Windows 7, making the Bootcamp 96 GB partition. I chose Custom installation and formatted the drive Bootcamp. The Windows installer completes the list of things to do (copy files, extension files,...) and then recharge.  Start Windows appears, and the window displays "end installation. Now that there where begins the strange behavior, I think. It restarts again. After that the Windows splash screen comes on, the screen goes black for a few minutes and then he recharges. This happens once again, but restarting does not, as if it is hung. I even let it run all night just in case she needed some time, but I found that it is always hanging in the morning. The computer was still on and the screen was black. I rebooted by pressing and holding down the power button, Windows starts showing the splash screen becomes black and crashes. ... I started Windows in safe mode, and he says that he cannot complete the installation in safe mode. So it seems that I am stuck. During all this the USB is plugged.

    Is there something I need to do to have it complete the installation?

    Note that I tried to install Windows using Bootcamp several times, varying from one thing at a time. as the withdrawal of all external drives, physically disconnected from the internet (I'm using a USB adapter to Ethernet because my Ethernet port was fried during a storm), etc. I also tried different ideas that I found on the internet, but none for those who work.

    Thanks in advanced for any help.

  • Clone HD on SSD (Imac mid-2011)

    Hi, I have an iMac mid-2011 with 1 TB of hard drive and I'll install a SSD 1 TB as a second drive. I think I will clone the HD on the SSD with Carbon Copy Cloner. My question is: can do the clone operation after installing the SSD inside the iMac to speed up the process or I clone the HD before the opening of the iMac with the SSD connected via USB? I have only USB 2.0, I think is going to be very slow in this way... Thank you, Francesco

    Install the internal SSD if that's your plan. Start the computer from the HARD disk, and then use disk utility to partition and format the SSD drive as follows:

    Clone El Capitan on a new disc

    1. Restart the computer. Immediately after the chime, press Command - R until the Apple logo and progress bar appear.
    2. When the Utility Menu appears, select disk utility and click on the continue button.
    3. When disk utility loads select the SSD (generally, the entry Out-bumpy) in the list aside.
    4. Click the Partition tab in the main window of disk utility. A panel will fall.
    5. Set the GUID partition scheme.
    6. Define the type of Format Mac OS extended (journaled).
    7. Click on the apply button, then click the fact when it is active.
    8. Select the new SSD, then select restore in the menu editing of disk utility.
    9. In the drop-down menu select the volume that you want to clone - your HARD drive.
    10. Click the apply button to start the process.

    This can take some time depending on the amount of data is transferred. Disk utility also automatically clones Recovery HD from the HDD to the SSD.

    2. Boot in single-user mode and fsck - fy
    3. Internet starts form Apple Hardware Test - no error at all!

  • can not start after the installation of 10 Windows via bootcamp OSX

    Hello, I need help.

    I tried to install 10 Windows via bootcamp, and I did it successfully with no problems. However, after the installation, I restarted my computer, hold down the option key and tried to boot into OS X, but it won't work. It would be a symbol that boot lead me to windows 10!

    all solutions? I do not have a backup of my files under OSX, I lose my files?

    NOTE: when I formatted the partition for windows, he said not bootcamp next to him, but it is clear that the partition that I had to format, it is the same size that I decided to make Windows when I was in bootcamp in OSX + it was empty at 100%.

    UPDATE 1: so I managed to get into the recovery of the internet and deleted the partition that had the windows and install OSX Marverix instead (temporarily) also, I fixed the hard drive MACINTOSH HD, but now I can't boot it at all when I press the option button during the priming of the mac. all solutions?
